“…Toward the end of 1980s, a comprehensive study on construction robotics showed that the automation of the crane should allow the improvement of the most frequent construction site operations (Elsila et al, 1988). At the time, concrete pouring was a frequent crane operation that can amount to up to 40% of all crane operations onsite, as in the example used in the present work.…”

PurposeThe crane plays an essential role in modern construction sites as it supports numerous operations and activities on-site. Additionally, the crane produces a big amount of data that, if analyzed, could significantly affect productivity, progress monitoring and decision-making in construction projects. This paper aims to show the usability of crane data in tracking the progress of activities on-site.Design/methodology/approachThis paper presents a pattern-based recognition method to detect concrete pouring activities on any concrete-based construction sites. A case study is presented to assess the methodology with a real-life example.FindingsThe analysis of the data helped build a theoretical pattern for concrete pouring activities and detect the different phases and progress of these activities. Accordingly, the data become useable to track progress and identify problems in concrete pouring activities.Research limitations/implicationsThe paper presents an example for construction practitioners and researcher about a practical and easy way to analyze the big data that comes from cranes and how it is used in tracking projects' progress. The current study focuses only on concrete pouring activities; future studies can include other types of activities and can utilize the data with other building methods to improve construction productivity.Practical implicationsThe proposed approach is supposed to be simultaneously efficient in terms of concrete pouring detection as well as cost-effective. Construction practitioners could track concrete activities using an already-embedded monitoring device.Originality/valueWhile several studies in the literature targeted the optimization of crane operations and of mitigating hazards through automation and sensing, the opportunity of using cranes as progress trackers is yet to be fully exploited.

“…The basic breakdown into four segments (i.e. without addressing the blind part of the cycle) differs also from the common breakdown into two segments only, loading/unloading and travel used by other researchers (Elsilä et al, 1988;Price and Harris, 1992;Leung and Tam, 1999). (Note that although the "start blind lift" time appears in Figure 1 to the right of the "start travel" time, the latter does not necessarily precede the former; this issue is addressed later in the "Integration and Validation" section.)…”

Purpose – This study aims to show how laser scanning data can be utilised to quantitatively assess “blind lifts” with respect to their rate and spatial distribution. Design/methodology/approach – This study employed time study of crane cycles for quantitative measuring of the crane’s work periods in dead areas and mapping the crane operator’s field of view and developing a model that allows the spatial analysis of blind lifts. Findings – This study found a discrete geometric laser scan-based model that is capable of locating and quantifying the visible and invisible zones from the crane operator’s cabin; 28 per cent of the analyzed crane’s work area represented by the model were found to be invisible, which corresponds fairly to 35 per cent of the half-cycles measured manually that were found to involve blind lifting; the range of blind lifts duration derived from the spatial information-based model was 50 to 84 per cent, which is in excellent correspondence with the 54 per cent to 82 per cent range obtained from the time unit-based analysis. Research limitations/implications – The laser-based model and the ensuing analyses are limited to the type of buildings whose envelope can practically be represented by the vertical extrusion of their footprint. Practical implications – The practical implications of the study are reduction of blind lifts as a factor when selecting the location of the crane and staging areas; more effective preplanning of signallers positioning; and ad hoc consideration of analysed dead space for various lift task-based decision-making during construction. Originality/value – This study demonstrates the ability to capture the geometric relations that characterise the work scene around the tower crane by harnessing the increasingly available laser technology and correlates the results of the manual observations with those obtained from the laser-based model.

“…It also assessed the prerequisites for automation (for a wider treatment of these, see [1]), the need for development of methods and technology as well as the profitability of automation applications. Emphasis was given to three stages that are central to the automation of the crane's working cycle: automation of gripping and releasing, automation of motion control and automation of load positioning.…”

This paper reports on the results of a Norwegian-Finnish feasibility project on construction robotics, carried out in 1988. The aim of this project was to determine and evaluate the most suitable robotization themes from the point of view of the construction industries in the respective countries. Functional requirements and preliminary technical solutions were charted for seven themes: crane automation ; automation of the prefabrication of facade components; robotization in inner works; equipment for materials handling on site ; masonry robotics ; concreting automation ; and measurement, positioning and navigation techniques in construction.
